I have a point layer in ArcGIS that has a field named "Population" that stores an integer value for every point in the layer.

I want to create N points in the exact place of the feature that has N as value in the population "field". I mean, if a point has in the population field 16, I need to create 15 more points in that exact lat long (1+15 so that there are 16 in total) of that point.

    Welcome to gis.stackexchange! Please note that a good question on this site is expected to show some degree of research on your part, i.e. what you have tried and - if applicable - code so far. For more info, you can check our [faq]. – underdark Aug 04 '15 at 17:33
  • This question may have had a [tag:qgis] tag (which I am removing) but asks only about ArcGIS in its body, and so I do not think it is a duplicate of the earlier QGIS Q&A. – PolyGeo Aug 04 '15 at 21:39
  • you can find the information on how to achieve this using python fairly easily with a few google searches. I'd suggest reading about 'search cursors' and 'insert cursors' as well as reading and writing the geometry of features from the 'shape' field. – Adam Aug 05 '15 at 00:37
  • You could do it in Excel using the attributes from your layer with the x and y fields calculated. Once you have manipulated the data in excel, you can then create the new layer using the excel table by using "Add XY Data" – TsvGis Aug 05 '15 at 02:15
  • That is great I did by Excel. I really appreciate. – Javad Koohpayma Aug 06 '15 at 00:41

As indicated in the comments the asker ended up using Excel as suggested by @TsvGis:

Personally, I would do this using ArcPy cursors, but using ModelBuilder could provide a more cumbersome alternative (iterators, Select, Copy, Append).

The principle is to iterate through the points and use the population field value to decide how many times to copy each.
